Nathan had an infection, and his doctor wanted him to take penicillin. Because Nathan’s father and paternal grandfather were all

Helga [31]

The probability that Nathan is not allergic to penicillin, like his father and paternal grandfather, is <u>24.5%</u>.

<h3>What is probability?</h3>

Probability estimates the likelihood of an event occurring.

Probability is expressed as a percentage, decimal, or fraction, and must be less than or equal to one.

<h3>Data and Calculations:</h3>

Nathan's chances of having the same allergy = 75%

Nathan's probability of not having the same allergy = 25% (1 - 75%)

Accuracy of test performed by the doctor = 98%

The probability that Nathan is not allergic to the drug after the test = 24.5% (25% x 98%).

Thus, the probability that Nathan is not allergic to penicillin is <u>24.5%</u>.

In the figure below , ABCD is a square . Points are chosen on each pair of adjacent sides of ABCD to form 4 congruent right tria

Lostsunrise [7]

Answer:

5/9 of the area of square ABCD is shaded

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

To find out what fraction of the area of square ABCD is shaded, divide the shaded area by the total area of square ABCD

step 1

Find out the area of square ABCD

The area of a square is

$A=b^{2}$

where

b is the length side of the square

we have

$b=(x+2x)=3x\ units$

so

$A=(3x)^{2}$

$A=9x^2\ units^{2}$

step 2

Find out the area of the 4 congruent right triangles

$A=4[\frac{1}{2}(x)(2x)]=4x^{2}\ units^2$

step 3

Find out the area of the shaded region

The area of the shaded region is equal to the area of square ABCD minus the area of the 4 congruent right triangles

so

$A=9x^2-4x^{2}=5x^{2}\ units^{2}$

step 4

Divide the shaded area by the total area of square ABCD

$\frac{5x^{2}}{9x^{2}} =\frac{5}{9}$

therefore

5/9 of the area of square ABCD is shaded
